  1. Innovation In AR Lens Coatings: High Quality Coatings For High-Power Lasers
    2/14/2019

    Lens coatings are an essential part of high-power CO2 laser systems. Coatings must protect the lens and allow for the highest levels of optical performance, with low levels of absorption and a long-life expectancy. Transparency is another coveted characteristic for use with visible HeNe red laser pointers. The cost/benefit ratio of a coating must also be considered, as well as the environmental impact of the substrates used. For optical manufacturers, the challenge is in developing a lens coating that excels in all these areas. This white paper discusses the development of anti-reflection (AR) lens coatings for use in high-power lasers.

  2. Semi-Transparent Mirrors For Visually Dynamic Hospitality Displays
    4/27/2018

    Hotel, restaurant, and retail owners are increasingly using aesthetically pleasing high-performance semi-transparent mirrors to create a visually dynamic display/mirror combination. These mirrors are constructed with a display unit hidden behind the glass that is not visible until powered on. 

  3. “Dynamic” Deadfront Interface Panel Glass
    4/19/2018

    A “dynamic” deadfront panel is used to create a sleek, uncluttered user interface appearance, drawing attention to the “hidden” light up indicators as required. The icons or other alpha-numeric indicators are visible when backlit, and when unlit, a monochromatic streamlined look is achieved. Abrisa Technologies offers complete solutions for deadfront panel glass technologies including screen printed graphics, chemical strengthening or heat tempering, anti-scratch coatings, and more.

  4. Optical Monitoring System Improves Thin-Film Coating Accuracy
    3/14/2018

    In the past, a thin-film design software was used to help develop the coating, but the real challenge was in actually replicating the design thickness and the material indexes inside the coating chamber, without any errors. 

  5. New Tool Measures 4 Surface Appearance Quality Conditions Simultaneously
    1/18/2018

    If surface appearance quality is critical to your product, learn about a new manufacturing-friendly tool that allows you to establish numerical standards for and measure four conditions of surface quality: gloss, haze, image clarity, and BRDF including Canon’s new parameter “Scattering C20, C60.” 

  6. How To Select A Spherical Lens
    7/6/2016

    Optical systems use lenses to focus, collimate, expand, collect, and image light. Ranging from convex to concave, and bestform to aspheric, any lens selection must be made with the utmost consideration for its purpose as well as its required quality. This white paper delivers a review of singlet spherical lens shapes, and guidance on deciding the best lens characteristics for each application.

  7. Specifying Optical Filters for Sensor Applications
    7/1/2016

    Each sensor application has its own subtleties that need to be addressed in order to choose the appropriate optical filters for each sensing task. This application note discusses the critical parameters for bandpass filters that are to be used for sensor applications, including considerations on in-band transmission, band edge placement, and out-of-band blocking.

  9. Technical Note: Guide To Glass
    6/30/2016

    Guide to Glass provides information about the types of glass and their associated thermal, optical, chemical, mechanical, and electrical properties; Understanding light & color; glare reduction; and glass Strengthening methods using heat and chemicals.

  10. Specifying Wavefront Or Surface Error In Aspheres
    5/12/2016

    The optical quality of aspheric mirrors is commonly specified by their surface accuracy and reflected wavefront error. The surface error is the deviation of the surface from its perfect form, while the wavefront error is the deviation of the resulting reflected or transmitted wavefront from its perfect shape. It is often assumed that these tolerances are related to each other by a simple scale factor. However, that is not the case when it comes to aspheric mirrors. This application note compares surface accuracy measurements with wavefront error measurements, and provides an application example on using them in off-axis parabolas.
